The analytical method of toxic heavy metals in disposable diapers was developed. Disposable diapers obtained from Korea, Japan, America and German were determinated and quantified. Sample treatment (Total Digestion) was wet chemical acid digestion for extraction of nine hazardous inorganic elements (Sb, As, Pb, Cd, Cr, Co, Cu, Ni, Hg) in disposable diapers. Inductively Coupled Plasma Mass Spectrometer (ICP-MS) and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) have been used for analyzing nine hazardous inorganic elements. The results were as follows : The concentration of extractable Sb which was treated for 3 hours with artificial urine and disposable diapers was higher than those of 6 hours and 24 hours. The concentration of extractable Cr was same as Sb. On the other hands, the behavior of Cu and Ni were different from Sb and Cr. Concentrations of extractable Cu and Ni increased as increasing the reaction time between artificial urine and disposable diapers.
